The goal of this study was to determine the effect that NP shape has on entropy produced by Al2O3−H2O nanofluid across a permeable MHD stretching sheet under conditions quadratic velocity, thermal radiation, and viscous dissipation. H2O is cold fluid, while nanofluid, which includes five various forms (oblate spheroid, platelet, blade, brick, cylinder), hot fluid. Nanofluid containing sees widespread use in industrial production because its remarkable capacity boost heat transfer. Via sequence similarity transformations, controlling PDEs are converted into nonlinear differential system linked ODEs. An efficient implementation Runge-Kutta method for getting numerical solutions may be found code, written MATLAB. As φ grows from 0% 2% or 4%, wall shear stress rises roughly 6.3% 12.6%, respectively, area behind stretched sheet. Including magnetic boundary layer flow at rate around 5%, convective transfer increases about 16.4%. In comparison nanofluids brick-, blade-, cylinder-, platelet-shaped NPs, Os-shaped experiences greater increase fluid side.
